Born Survivors: Sand People are raised in the desert and tempered by it, making them capable of surviving in environments far tougher than most species can. This gives them a bonus +2D to all Survival checks.
Dry: The Sand People manage their water use because of the arid environment they come from, only requiring 50% of the water that most species require.
Technological Distrust: Stories from ancient Storytellers of the Tusken speak from a disaster on Tatooine long ago, the Tusken had made there living under the surface of the planet and returned as survivors to the desert. As a result Tusken distrust High-Tech and get a strong survival feeling of unease around it.
Masked: Due to their harsh environment, Tusken Raiders always go masked and robed to save every drop of water. This has become almost religious to them, as they cover themselves at all times and do not show their faces except at very special times such as marriage and child birth.
